Abstract: At present India is stepping towards becoming a global super power. This implies that it is leading the list of developing countries in terms of economic development. Therefore the energy requirement of the country would increase in rapid rate. At present there is existing blade windmill to produce energy, but its capital cost, maintenance cost, friction loss is high. So in our project we are going to generate electricity by using BLADELESS WINDMILL. Bladeless wind generation uses radically a new approach of capturing wind energy. It works on principle that when wind is allowed to strike the column mast, it tends to vibrate and this vibrational energy is further converted to mechanical energy. The spring is provided inside mast which is connected to crank shaft. The vibration is transmitted to crankshaft which is then supplied to generator. It is an eco friendly project and it reduces the friction losses. Keywords: Bladeless Windmill, Vortex Induced Vibrations. Spring 1. Introduction In these days non renewable energy sources are gone to the depth of earth, so we can obviously produce energy by renewable energy sources. Wind energy has became a legitimate source of energy over the past few decades. The construction of bladeless windmill is quiet simple. The conical mast is pivoted vertically with the help of cylindrical rod which is held within roller bearing in such a way that it vibrate in one direction only. The portion below pivot is covered with help of metal sheet. The upper part of mast flutters in wind while crank shaft is connected to lower part. Figure 1. Vortex windmill This is a wind generator without blades. The main advantage of this underlies the absorption of energy through the vortices of a rigid member similar to an effect of aerodynamics.We are going to generate electricity by using the bladeless windmill. This wind mill will have no blades. It will generate electricity by using oscillation due to wind. 2. Problem Identification The rate of wind power developed founds costly when compared to an existing wind mill. For these several invetigations need to be found out. Some of identifications are as follows:  Higher capita expenditure in observed in erection and commisioning of a wind mill. Conventional windmill requires places where wind speed is more. Such places are limited. Hence windmills working on lesser wind speeds are need of the hour.  The cost of manufacturing different parts of windmill is very high. A typical windmill will cost $3000-$8000 per kilowatt.  So also the transportation of such huge parts is very costly and risky. If during transportation components get damaged then again cost increases.  Designing of windmill blades is also a big task.  The size of the assembled windmill is also very large. The conventional windmills occupy lots of space. The commercial turbines can be 160m high.  Area of installation is 60 acres per megawatt of capacity of wind farms.  Also they prove fatal to birds.  They produce low frequency sound which is not good for human health. 3. Methodology Methodology is the basic requirement for a project, because it defines the proper start and end condition of the works to be done. Proper planning and execution of the workflow decides the successful completion of the project. The methodology of this project is as follows.
